I haven't used sunpos.inc, but if you need the position vector of a
translated/rotated point, you can get it with vector functions. For example,
vrotate(<XTrans,YTrans,ZTrans>,<XRot,YRot,ZRot>) returns the new coordinates
of a point <XTrans,YTrans,ZTrans> rotated around the origin by
<XRot,YRot,ZRot>.
Just apply the same translation/rotation as the ones in sunpos and you get the
point you need.
